According to the README, it hands the tasks that need no text output to Jev, which the GitHub description calls TypeSafe's judgment model. The README says that when content needs to be written the LLM takes over, and when a step only needs a decision Jev executes it.\n\nThe README's library example asks Jev three kinds of question: check, pick and rate. The example result for one question holds the answer, a confidence and an escalate flag. The README says anything Jev can't or shouldn't decide comes back with escalate set to true and a typed reason. It shows four demos, such as gating shell commands and context compaction, and points to bench/RESULTS.md for numbers, methodology and caveats.\n\nThe repository holds the TypeScript source, including the code for the two MCP tools, a routing skill at skills/jev-use, plugin forms for Claude Code and Codex with that skill and a PreToolUse gate (harness/claude-code and harness/codex), benchmarks and demo scripts. The README lists what each source file does.","intended_users":"People who use Claude Code, Codex or pi and want to hand quick decision steps to Jev.","example_tasks":"Run the install command to wire Claude Code, Codex and pi, whichever it finds.\nRun a keyless dry run with the mock backend.\nCheck the wiring with the doctor command.\nAsk Jev check, pick and rate questions about a run's state from code.\nRerun one of the demo scripts in bench/examples.","setup_instructions":"The README's install command is npx -y jev-use install, which it says wires Claude Code, Codex and pi, whichever it finds. Set one key in the environment your agent runs in: TYPESAFE_API_KEY, OPENROUTER_API_KEY or AI_GATEWAY_API_KEY. Use JEV_BACKEND=mock for a keyless dry run. The README says npx -y jev-use doctor checks the wiring. For library use it shows npm i jev-use. The README has the exact commands.","limitations":"Real use needs a key for one of the three Jev providers the README names (TypeSafe direct, OpenRouter or Vercel AI Gateway). The README's keyless dry run uses the mock backend. It presents the tool for Claude Code, Codex and pi. The README presents speed, token and quality claims alongside its demos. It points to bench/RESULTS.md for numbers, methodology, variance and caveats, and to docs/evidence.md for third-party measurements. The repository can change at any time; check its README before you install.","data_handling":"According to the README, judged state goes to the provider you configure, while JEV_BACKEND=mock stays local.
